Cuprite and Cryolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cuprite and Cryolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cuprite and Cryolite Optical Properties during the identification of gemstone. Specific gravity of Cuprite is 2.97 whereas that of Cryolite is 2.97.
